If you are using buster-amd, you don't need buster-coffee to compile
your CoffeeScript files, but can instead use e.g. the require-cs AMD loader
plugin. See the demo-amd/ dir for an extensive example project, using
Buster.JS to test AMD modules written in CoffeeScript and loaded with
RequireJS.

Currently, buster-coffee does not work with files that are to be included using
require(). buster-coffee never writes any files to disk, while require()
explictly looks for the files it will include on disk. Because of this,
buster-coffee has limited use for Node.js development in CoffeeScript.

Set the ETag on the generated JavaScript resource to the same as the original
CoffeeScript resource. This ensures that any generated JavaScript cached by
Buster.JS will be invalidated when the CoffeeScript source changes.
